CHEYENNE, Wyo. (AP) — The Legislature's Select Investigative Committee has heard three days of lengthy testimony in its investigation of state schools Superintendent Cindy Hill.

However, there's still no clear end in sight.

The committee is investigating a number of issues and allegations that arose from Hill's administration of the state Education Department in 2011 and 2012.

Hill has denied any wrongdoing and says the investigation is a waste of time and money.

Still, Hill has submitted a list of 38 witnesses she wants the committee to call.

House Speaker Tom Lubnau, who chairs the committee, says he will review the list and work with the committee on how to proceed.

The committee is to issue a final report that can recommend whether the full House should consider impeachment of Hill.
